Abstract: PURPOSE:To omit the calculating time needed for conversion of addresses and to perform the conversion of images at a high speed by operating the address of the image data and carrying out the address conversion processing of images when the image data stored in an original image store memory to a display memory. CONSTITUTION:When the image data stored in an original image store memory 1 are transferred to a display memory 2, the address processing of the image data is carried out and the image address conversion processing is carried out. At the same time, the result of calculation obtained by an address calculation/write circuit 7 for calculation of the address of a memory 1 corresponding to the address of the memory 2 is written into a row address memory 5 and a column address memory 6. Then an address generator 4 produces the write address of the memory 2. Thus the address conversion processing is carried out. In such a way, the address of the memory 1 corresponding to the address of the memory 2 is produced at a high speed. For this purpose, both memories 5 and 6 which store the row and column addresses of the memory 1 are used. As a result, no calculating time is needed for conversion of addresses and the images can be converted at a high speed.
